Quoted from ViperTim:Thanks all.
I am starting to suspect I have power issues.
Just a theory.
My wife noticed today that sometimes the flippers become sluggish and can’t even shoot a ball properly. Same with the plunger that cannot even get the ball out on the playfield - sometimes.
Also noticed absolutely zero flipper action on both left and right at the same time and also long delays from button push until flipper activates.
I need to try it myself but I am starting to suspect power issues here… But it feels like something else should go before this occurs but I haven’t dealt with power boards at all before so I don’t know what I’m talking about.
Does my hypothesis make any sense or am I completely lost in the wild?
If you have other coils that are week in addition to the flippers, I’d start checking the power boards capacitors. Unless all your coils are dirty and need maintenance (flipper rebuild, mushroomed plungers and dirty/broken coil sleeves)

Quoted from Bulskis9298:I replaced the diode and still same issues?
did you check to see if you have a diode Inside your light socket. I had something similar happen to my Stern Simpsons
Quoted from Bulskis9298:Diode was replaced with the band facing the same direction it was removed, I also noticed that the extra ball button light is very dim when I remove the bulb from 55
Confirming everything works as it should if you remove the light from 55?
Quoted from Bulskis9298:Diode was replaced with the band facing the same direction it was removed, I also noticed that the extra ball button light is very dim when I remove the bulb from 55
Since you have 2 string of lights that are acting up that intersect with the #55 socket, I would assume there’s something wrong with your socket. Can you take a picture of your light socket and diode. Also the led bulbs your using.
You can try putting incandescent bulbs in again and see if there’s any changes.
Quoted from Bulskis9298:Yes everything works as it should when bulb is removed with the exception of the extra ball button light is very dim when bulb is removed, Same issues if I put a incandescent bulb back in. I can take a pic of it tomorrow when I get done work.
My best guess is you have a short in your socket. Install a new one or swap it with another and see if the problem moves with it.

Quoted from petrieslastword:I've been trying to troubleshoot why my Monday Night Football occasionally kicks out two balls, and the only thing I'm noticing in the switch test compared to the other switches is there seems to be just a tiny delay when I press those switches from when they register. Every other switch seems to be instantaneous. It's like a half a second or less but I'm sure this is what's causing the issue. Any idea what would cause that kind of delay? I'm a little at a loss.
I tried replacing all of the capacitors on those switches with new ones but that did not fix anything.
To elaborate with a little more detail: The first switch which is the out hole switch works fine. It's the trough 3 and then each switch after that that have the delay. Replacing the capacitors on those switches did not help. It's like a half second delay after you press it and then a half second delay before it stops pressing when you let it go.
The switch is probably old and dirty. I’d replace it.
Quoted from petrieslastword:It's not that. 2 of them are brand new a few months back, and multiple switches in the sequence have the exact same issue. The outhole is good, but trough 3, 2 & 1 all have the same weird delay.
Look and see if those switches line up in a row or column on your switch matrix schematics. If so, you should have a couple more dedicated switches to that row/column. Then check and see if those other switches have the same delay problem.
If this is the switch column/row in line with each other:
It goes out hole, trough 1, 2, 3, shooter Lane, Left EOS, Right EOS.
Then your problem is a switch if you don’t have problems with the other 2 switches. Did you say you put a capacitor on a switch or was it a diode?
In my experience, when 2 balls kick out it’s usually a trough switch problem.
When testing your switches, are you removing the apron and testing them from the top of the play field? Make sure the trigger bar of the switch has enough rise above the play field and is not bent or getting stuck when it moves up and down. Also, the switch in the first picture looks old and suspect. I’d replace that switch and the diode. I would personally replace all switches from the beginning of trough to shooter lane. I believe you said a couple were already replaced, but your shooter lane looks old and gummy. If your shooter lane is not detecting a ball immediately it will kick out a second ball.

Quoted from redmerlin:Just picked up a Batman and it needs a DMD… anyone upgrade to a color unit and want to sell your old one?
I have a couple Stern Simpsons dmds, don’t know if it’s the same one or not. They’ll fit into my Williams Dracula.
